Synthesis of 1,2,3-triazolo[1,5-<i>а</i>]pyridin-8-ium-3-olates

Abstract

Alkylation of sodium 4-acetyl-1-phenyl-1,2,3-triazol-5-olate with α-bromoacetophenones was shown to occur at position 3 of the heterocycle, with the formation of 1,2,3-triazol-3-ium-5-olates. Intramolecular crotonic condensation of the latter led to the formation of 1,2,3-triazolo[1,5-а]pyridin-8-ium-3-olates.
